Abstract: 29,282. Hocquart, E. L. Dec. 22. Lifts.-Relates to travelling stairways of the kind described in Specification No. 2231, A.D. 1905, and comprises special arrangements of the guides at the receiving and depositing ends of the stairway, and improvements in the hand-rail. In the present form, the receiving comb-like platform 12 is formed as a fixed step, and the guides 11, 13, 14 are disposed so that the travelling step ascends vertically through the receiving - platform. By this arrangement, it is not possible for a passenger to step on to the receiving-platform without the whole of his feet being engaged by the ascending step. At the depositing end, guides 9, 42 are disposed so that the forward edge of each step passes beneath the receiving-platform first, and the plane of its surface always intersects the platform at a fixed line x. With this arrangement, the toe of the passenger is deposited first and he is induced to take a step forward. If this be not the case, the toe is pushed forward until the whole foot is deposited clear of the steps following. The moving hand-rail, Figs. 10 and 11, is constructed as before but is secured to an endless steel band 32, to which are riveted, at intervals slide pieces 34 with the interposition of india-rubber chocks 33. The band 32 passes over two smooth pulleys 30 having central grooves 41 to permit the passage of the slides 34.

Granted: 1907-06-13
Abstract: 2993. Gminder, E. Feb. 8,1906, [date applied for under Patents Act, 1901]. Loom let-off motions. - Relates to warp - beam brake mechanism and consists of a band brake, the arc of contact of which is arranged to diminish so as to decrease the friction as unwinding of the warp proceeds. The weighted band brake 3 is attached to a segment 7 gearing with a pinion 8 on a shaft 9 carrying a pinion 14. The pinion 14 gears with a segment 13 on a shaft 10 carrying an arm 11 provided with a roller 12, which is pressed against the circumference of the beam 1. As unwinding proceeds, the segment 13 moves to the right, and the segment 7 turns in a clockwise direction, thus decreasing the arc of contact of the band 3. By suitably arranging the axle 6 of the segment 7 relatively to the axis of the warp beam, the rate of decrease of the braking-mechanism can be arranged to diminish more or less quickly at the beginning or at the end of the winding-off of the threads. The brake, segments 7, and pinions 8 are duplicated. Yarns, warping.-The Specification in the original form as published under the act of 1901 describes the application of the brake mechanism to warping- machines. This subject-matter does not appear in the Complete Specification as accepted.

Granted: 1908-04-23
Abstract: 14,021. Jordan, W., [Hyatt Roller Bearing Co.]. June 18. Surfacing; producing curved surfaces.-In a machine for grinding cylindrical articles, particularly spirally wound cylindrical springs for use in roller bearings, the work is mounted in radial positions on an intermittently rotating carrier and is operated upon by the opposing faces of two grinding-disks. The disks are automatically separated to allow the carrier to rotate to bring a fresh piece of work into the operative position, and the carrier is moved to prevent the work from touching either disk during such placing operation. The rollers &c. if hollow are loosely mounted on mandrels w Fig. 7, arranged radially around a carrier v, or, if solid, in radial slots 25, Fig. 1<b>, in a carrier 24. The carrier v is mounted on a shaft x, intermittently rotated by a pin on a notched disk 1, Fig. 1, engaging the toothed wheel z of a Genevastop arrangement, and is arranged so that the work projects between grinding-disks d, d', driven at different speeds through pulleys 12. The grinding- disk d is held in bearings b and is incapable of longitudinal movement. The grinding-disk d' is mounted in bearings g on a support g<1> and is pressed forward against the grinding-disk d by a spring 16, Fig. 6, which engages an antifriction collar 15 on a sleeve 18 on the shaft h and also a nut 17 on a threaded sleeve 19 sliding over the sleeve 18. A nut i on a threaded portion of the shaft is adjusted to come in contact with the bearing g and act as a stop to determine the size of the finished article. The grinding-disk d' is automatically withdrawn from the disk d when the carrier v is to be rotated to bring a fresh piece of work into position by a bell-crank lever k, one arm of which embraces pins j on a swivel block m which abuts against an adjustable nut n on the shaft, and the other arm of which is raised - by an extensible rod s operated by a cam t on the shaft q. The shaft q is driven from the main shaft 3 by chain gearing which is so arranged that the shaft q rotates once for each movement of the shaft x. Rollers 6 mounted on one of the bearings 10 of the shaft x normally engage grooves 7 in the carrier v, and, when the carrier is turned to bring a fresh piece of work into position, operate to push the work that has been ground away from the grinding-disk d against the action of a spring 8. A guard having a curve edge concentric With the carrier shaft may be provided between the grinding disks to prevent any material displacement of the work along the mandrels w. To compensate for the greater wear of the disks at their outer edges, the support g<1> for the grinding-disk d<1> is arranged to swivel on the frame a, and can be locked iu position by bolts p.

Granted: 1908-04-23
Abstract: 21,827. Latour, M. C. A. Oct. 3, 1906, [date applied for under Patents Act, 1901]. Field magnets; sparking, preventing.-To obtain good commutation over wide ranges of speed, the voltage impressed upon the auxiliary commutating windings of single-phase series commutator motors is the resultant of two opposing voltages, of which the smaller increases with increase of speed, so that the strength of the commutating field decreases with increase of speed. In one arrangement, Fig. 1, the commutating winding D has impressed upon it two voltages V, V<1>. The voltage V<1> is derived from a phase converter of the induction or repulsion type, Fig. 3, the primary winding g' of which is connected in series or in shunt to the motor. The second voltage V is derived from the terminals of the armature A and compensating winding C. In a modification, Fig. 4, the voltage V<1> is derived from the terminals of a resistance E in series with the motor, the armature voltage being also impressed upon the winding D through a transformer F.

Title: Improved Device for Accelerating the Application of Pneumatic Brakes.
Inventor: CHAPSAL FRANCOIS JULES
IPC: B60T15/42
Filed: 1907-11-21
Granted: 1908-03-19
Abstract: 25,820. Chapsal, F. J., and Saillot, A. L. E. Dec. 11, 1906, [date applied for under Patents Act, 1901]. Brakes.-In continuous air-pressure brakes, the distributing-valve of each car is provided with a local venting-valve, which is opened, when a reduction of train-pipe pressure takes place, by the trainpipe pressure acting on one side of a diaphragm connected to the valve, and is closed by compressed air in a supplementary reservoir acting on the other side of the diaphragm. The accelerator is described in connexion with the distributing-valve described in Specification No. 29,120, A.D. 1904, and comprises two chambers 1, 2, Fig. 1, separated by a diaphragm 3 which carries the valve 4 controlling the exhaust port 5. The chamber 1 communicates through a restricted passage 7 and passage 6 with the distributing face of the slide valve F, and the passage 6 has a branch 8 leading to the distributor chamber G. The chamber 2 communicates through a restricted passage 10 with the distributor chamber H, and through a passage 9 with the valve F. The piston I of the slide valve is provided with a chamber J normally closed by a spring check valve K. With the parts as shown in Figs. 1 and 3, air is feeding from the train-pipe A to the supplementary reservoir E and to the braking reservoir D, and the cavity in the valve F connects the passages 6, 9 leading to the chambers 1, 2, and the passage 13 leading to the brake cylinder, to the exhaust 12. When a reduction in pressure in the train-pipe occurs, the slide valve F moves to the position shown in Fig. 4, in which the train-pipe port 11 connects with the port 9, and air flows into the chamber 2 and raises the valve 4, opening the trainpipe to atmosphere. At the same time the port 6 is uncovered to the pressure in the supplementary reservoir E, but owing to the restricted passage 7 a certain time elapses before the pressure in the chamber 1 is sufficient to close the valve 5. If the reduction of train-pipe pressure is greater than that desirable for producing a maximum braking effect, the valve K is opened against the action of its spring, and allows air to pass from the reservoir E to the train-pipe through the passages L, M. The accelerator may be combined with any distribution valve, and in the Westinghouse brake, the triple valve is arranged to connect the reservoir E to the chamber 1 as soon as the triple-valve piston is depressed, the chamber 2 being at the same time connected to the train-pipe through a passage of larger section.

IPC: H02P7/34
Filed: 1909-04-20
Granted: 1910-04-14
Abstract: 9338. Felten & Guilleaume-Lahmeyerwerke Akt.-Ges. Nov. 30, 1908, [Convention date]. Boosting.-In an electric distribution system, having a motor which it is required to reverse quickly, a subsidiary machine is placed between the source of current and the motor, the windings of such machine being arranged to limit the current through the motor when the latter is suddenly reversed. The subsidiary machine b driven by the motor a is placed between the source e and the driving-motor m. The machine b is provided with a shunt winding g, a series winding h, and a winding f excited by the source e. Under normal conditions of running of the motor m, the windings f, g act in conjunction against the winding h, thereby causing the machine b to assist the source e. When the motor m is suddenly reversed, the winding h predominates over the windings f, g, thereby reversing the polarity of the machine b and causing the windings h, g to act in conjunction against the winding f. The maximum value of the current through the motor m is adjusted by means of the regulator r in circuit with the winding f. The motor m may be series, shunt, or compound wound, and may be reversed by changing the armature instead of the field connexions. As described in Specification 23,216/07, the field windings f, g may be replaced by a single winding to which the sum of the pressures of the source e and machine b is applied, while the current in this winding is regulated by the attendant. The arrangement is specially applicable to the propulsion of submarines.
